2 Claims,

The invention relates .generally to tear strip or c ollar cans .and `primarily kseeks toprovidea novel form of collar ,and novel mounting therefor.

In can structures-ortho character stated, the can body-isp providedwith a tear strip adjacent the upper end thereof which can be wound about a key and thus torn from the can body to separate the upper extremity orf the can body .and the attached top end closure from the main body of the can thereby to effect an opening of the can. It is customary to kprovide a Acollar within and extending from the lupper extremity of the can body left by tearing out the tear st 'pso ias to provide an upward extension -.over w nth@ skirt depending from the removed topclosure of `the cancan be telescoped in vorderto eiect a reclosure of the can. According to thelpresent invention, there is provided a collar including a main cylindrical body portion terminating at its upper extremity in an inwardly directed curl, and at its lower extremity in an inwardly bent portion merging into an outwardly b'ent portion, and the can body is provided with an outwardly directed bead into which the outwardly directed lower end extremity of the collar is outwardly bent in a manner for anchoring the collar in the upper end of the can and also for so disposing the raw edge at the lower end extremity of the collar as to assure against Contact of said raw edge by the hand of a user of the can.

With the above and other objects in View that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims, and the several Views illustrated in the accompanying drawing.

In the drawings:

Figure l is a side elevation and part vertical cross sectional view illustrating a can embodying the invention.

Figure 2 is an enlarged fragmentary vertical cross sectional View illustrating the collar per se.

Figure 3 is an enlarged fragmentary vertical cross sectional view illustrating the collar of Figure 2 mounted in a can of the form illustrated in Figure l.

In the example of embodiment of the invention herein disclosed, the collar is shown as mounted in a can comprising a body 5, a lower end closure 5 and an upper end closure l. The can body is provided adjacent' its upper end with a bead structure comprising an outwardly extended upper bead portion 8 and an inwardly extended lower bead portion 8. Just above the S-shaped bead portion 8, 9 the can body is scored in the y.torn outof the canjbddyto separate the main '2 manner welllgnown in thewart to prpyide a tear emp it .widen when .wound about .a key may??? portion of the body from the upper thereof and effect an opening of thercfalnv y the tear strip l Eiis torn ,o ut inthe manner stated, a skirt il ,Y is vle,ft',,attached to the c upper l end t c lqsure ii, ,and this .skirt isladantedtplbe telescope@ riverine' .collar which projects from theupner .extremityof the main .can bodyinnrdeio. effet Vva reclosure Y of the can.

Before. the .collar is inserted in .tibetanii :Com-

- prises. a cylindriform body; portion ,l 2 and .an Wardl-y .curled upperextremity lL3 in the ner illustrated in Figure 2, Vand `this collar is .,telescoped into the .upper .end lof thecanbpbclyiin .ely

position. for extending thereabove .when the `teyar strip lil is torn out in the manner above described. After the collar has been inserted in the upper end of the can body, the lower end portion thereof is mechanically bent outwardly into the upper, outwardly extended bead structure portion 8 with the lower edge thereof abutting the juncture l5 between the outwardly directed bead structure portion 8 and the inwardly directed bead structure portion 9. By thus bending the lower end extremity of the collar l2, it is disposed in the form of a positive stop which c engages in the upper bead [portion outwardly of the juncture l5 between the bead portions 8 and or in other words outwardly of the diameter of the can body 5 in a manner for definitely placing and preventing a downward displacement of the collar. This placement of the lower and extremity lfl of the collar l2 also serves to present the inwardly directed bead structure portion 9 as an edge guard which will prevent contacting of the raw edge of the collar l2 .by the hand of a user of the can. It will be apparent by reference to Figure 3 that the outwardly bent lower end extremity lli of the collar l2 contacts, as stated, outwardly of the juncture I5 of the bead structure portions 8 and 9 and at such an angle that downward pressure on the collar I2 will tend to expand the collar end portion M and thus render even more positive the stop Contact of said collar extremity with the S-shaped bead structure 8, 9.

By providing the S-shaped bead structure 8, 9, the individual outwardly and inwardly directed bead portions 8 and 9 can be made relatively shallow so as to avoid the necessity of forming exaggerated bends in the multiple wall thicknesses of the can body at the position of the can body side seam.

yIt is to be understood that the collar herein disclosed may comprise an endless band such as would be formed from a drawn ring, or it may be shaped from a strip joined at its ends in an approved manner. An example of the last mentioned type of collar is shown in the copending application for U. S. Letters Patent Serial Number 543,655, led by William F. Punte on July 6, 1944, now Patent No. 2,403,192. When collars formed from end joined strips are employed, the joint or seam disclosed by Punte will be found desirable because in this form of joint or seam the multiple thicknesses ofV collar band metal are disposed only at the central oylindriform body oi the collar and no overlapping of wall thicknesses is presented at the upper edge curl or the lower edge bend portions of the collar.

While one form of the invention has been shown for purposes of illustration, it is to be 'clearly understood that various changes in the details of construction and arrangement of parts may be made without departing from the spirit .and sco-pe of the invention as dened in the appended claims.

We claim:

1. In a sheet metal container, a body portion, an upper end closure seamed onto the body portion, said body portion having an S-shaped bead structure adjacent its upper end including an outwardly directed upper bead portion and an inwardly directed lower bead portion, the body portion between said upper bead portion and the closure being scored to provide a, tear strip, and a collar snugly fitting within the body and having a main body portion lying opposite and extending above and below the tear strip and a lower raw edge extremity turned outwardly as an anchor 4 into the upper bead portion and into position for engaging as a collar limiting stop against the upper bead portion outwardly of the diameter of the container body portion.

2. In a sheet metal container, a body portion, an upper end closure searned onto the body portion, said body portion having an S-shaped bead structure adjacent its upper end including an outwardly directed upper bead portion and an inwardly directed lower bead portion, the body portion between said upper bead portion and the closure being scored toY provide a tear strip, and a collar snugly tting within the body and having Y a main body portion lying opposite and extending REFERENCES CITED The following references are of record in the file of this patent:
